Planning commission OKs Luxstone rezoning, approves proffers that preserve blast vibration limit
Summary
The Powhatan Planning Commission recommended approval of Luxstone Corporation’s rezoning to mineral and mining extraction for a 15.2-acre parcel and accepted updated proffers that keep an existing 0.1 inches-per-second vibration limit while removing an older per-shot poundage cap.
The Powhatan Planning Commission recommended approval of rezoning case 25-02-REZ-C on March 4, voting to rezone a 15.2-acre parcel (Tax Map 42-7H) from heavy industrial to mining and mineral extraction and to replace existing proffers with those dated Feb. 14, 2025.
The proffers accepted by the commission keep the existing peak particle velocity limit of 0.1 inches per second at the nearest seismograph and do not change the quarry’s permitted number of blasts per week or truck counts, but remove the earlier 15,000-pound cap on total explosives per shot in certain phases. Planning Director Jad Webb presented the request and the staff recommendation for approval.
Why it matters: The change lets Luxstone consolidate on-site overburden storage for projected future excavation while updating proffers to reflect modern blasting practice, and preserves an operational vibration limit that county staff and the applicant said will continue to protect nearby residences.
Luckstone representatives described the request as two parts: rezoning the parcel to allow permanent on-site overburden placement and amending proffer number 7, which had limited the total weight of explosives per blast in portions of the quarry. An applicant representative explained, “Overburden is basically a layer of soil or dirt that we strip from the top of the rock,” and said the company expects roughly 2,000,000 cubic yards of material over the next 20–25 years and prefers to keep that material on-site.
The applicant and company blasting manager, George Fields, explained that modern electronic detonators and blast‑modeling software allow precise timing of individual holes and reduce the correlation between total shot weight and ground vibration. Fields told commissioners that electronic detonators allow timing control “within a quarter of a millisecond,” and the company’s monitoring data show no direct correlation between shot weight and vibration at the Old Powhatan Estates seismograph.
One nearby resident, Carl Schwendeman of 1727 Theresa Lane, said he did not object to an on-site storage area but asked whether a mechanism could restore the previous poundage restriction if blasting became a nuisance. A commission member and the planning director said annual reports and county enforcement provisions in the proffers would provide oversight; a county representative confirmed the proffers require annual reporting and that the county can act if vibration limits are exceeded.
Commission action: Commissioner Hatcher, whose district includes the site, moved to recommend approval “based on public necessity, convenience, general welfare, and good zoning practice,” using the motion text read into the record; the motion was seconded and carried on a roll call vote (Hall — Aye; Boland — Aye; Winnall — Aye; Hughes — Aye; Hatcher — Aye). The commission’s recommendation forwards the rezoning and the proffers dated Feb. 14, 2025 to the Board of Supervisors for final action.
Ending: The applicants said there is no change to the quarry’s production capacity, weekly blast count (limited to five per week in the proffers), truck volume, or the 0.1 inches-per-second vibration standard. The applicant and staff said the updated proffers are intended to modernize how the quarry meets that standard rather than relax it.
